In Bridge Mode, connect the single speaker to the terminals marked “R +” and “L+” ensuring that the “L+” is connected to the “+” terminal on your loudspeaker and the “R+” is connected to the loudspeaker’s “-” terminal.
CHANNEL A OUT is a line level “loop through” output. The same level of input signal at the CHANNEL A IN sockets is available at CHANNEL A OUT sockets thereby allowing the same signal to be shared or passed on to another amplifier.
5 BRIDGE MODE (applicable to CHANNEL A only): The C 245BEE amplifier can be configured to be MONO (Bridge Mode), more than doubling its output power. This way, the C 245BEE can be used as part of a high power stereo or home-theatre system, by connecting additional power amplifiers. In BRIDGED MODE, the C 245BEE will produce approximately 70W into an 8 ohm loudspeaker. In this mode, the amplifier sections will react as though the speaker impedance has been halved. Low impedance speakers (under 8 ohms) are not recommended when using Bridge Mode as these may cause the amplifier’s thermal cut-out to operate if played at high levels.
NEDERLANDS
1 CHANNEL B SPEAKERS (applicable to CHANNEL B only): Connect the right speaker to the CHANNEL B SPEAKERS terminals marked “R +” and “R-” ensuring that the “R+” is connected to the “+” terminal on your loudspeaker and the “R-” is connected to the loudspeaker’s “-” terminal. Connect the terminals marked “L+” and “L-” to the left speaker in the same way.

ESPAÑOL
7 +12V TRIGGER IN/INPUT SENSE - OFF/AUTO: This dual function switch alternates between sensing a +12V input as applied through the +12V trigger IN jack or sensing any input signal applied at the CHANNEL A IN or CHANNEL B IN sockets.
ITALIANO
At AUTO setting and with the +12V trigger input of the C 245BEE connected to the DC output jack of a compatible auxiliary component, the C 245BEE can be switched remotely from standby mode to ON and vice-versa. Use a 3.5mm mini-jack to pass +12V from the auxiliary equipment into the C 245BEE. If there is no 3.5mm mini-jack inserted at the +12V Trigger IN jack and with the switch still at AUTO setting, the C 245BEE will instantaneously turn ON from standby state if it senses any input signal (approximately above 20mV RMS input) applied through CHANNEL A IN or CHANNEL B IN sockets.
DEUTSCH
In the absence of a +12V trigger input or any input signal at CHANNEL A IN or CHANNEL B IN sockets and with OFF/AUTO switch set to AUTO, the C 245BEE will switch automatically to standby mode. Slide the OFF/ AUTO switch to OFF setting for the C 245BEE to be normally switched ON (or back to standby mode) using the front panel STANDBY button.
NEDERLANDS
IMPORTANT NOTICE With the rear panel POWER switch at ON position and the OFF/AUTO switch at AUTO setting, the C 245BEE cannot be switched ON using the front panel STANDBY button. Slide the OFF/AUTO switch to OFF setting for the C 245BEE to be normally switched ON (or back to standby mode) using the front panel STANDBY button.
SVENSKA
NOTES • Switch the rear panel POWER switch to ON position in order to make use of the +12V Trigger IN or Input Sense AUTO feature as well as the front panel STANDBY button. • It will take about 10 minutes for the C 245BEE to go to standby mode when the input signal source is turned OFF.
РУССКИЙ
8
8 +12V TRIGGER INPUT: The +12V Trigger input allows the C 245BEE to be switched remotely from standby mode to ON and vice-versa by ancillary equipments such as a preamplifier, AV processor, etc. The controlling device must be equipped with a 12V trigger output to use this feature. Refer also to the section above about “+12V TRIGGER IN/ INPUT SENSE - OFF/AUTO”. 9 FUSE HOLDER: In the unlikely event a fuse may need to be replaced, unplug the AC cord from the wall. Then, remove all connections from the amplifier. Use a flathead screw driver or similar to open the fuse holder via the slot indicated. With the screw driver in place, push and turn counterclockwise to open the fuse holder. Only replace the fuse with the same type, size, and specification – T3.15AL 250V for 230V version or T6.3AL 250V for 120V version. IMPORTANT NOTICE Do not use any substitute fuses of different types or with different ratings or values. Failure to observe this precaution may cause damage to the amplifier circuits and may create a fire hazard and/or defeat the safety built into the amplifier and may void the warranty. 10 AC MAINS INPUT: The C 245BEE comes supplied with a separate AC Mains cable. Before connecting the cable to a live wall socket ensure that it is firmly connected to the C 245BEE’s AC Mains input socket first. i.e., 120V 60 Hz (for 120V version models of C 245BEE only) or 230V 50 Hz (for 230V version models of C 245BEE only). Always disconnect the AC Mains cable plug from the live wall socket first, before disconnecting the cable from the C 245BEE’s Mains input socket. 11 POWER SWITCH: The POWER switch supplies the master AC mains power for the C 245BEE. Refer to the ATO LOGIC chart below for a better understanding of the role of the POWER switch when switching ON or OFF the C 245BEE. If you intend not to use the C 245BEE for long periods of time (such as when on vacation), switch OFF the POWER switch.
IDENTIFICATION OF CONTROLS
the same manner by which it was activated. In other words, if the C 245BEE is switched ON via a +12V-control signal, it cannot be switched to standby mode via the front panel STANDBY button, it must wait for removal of the +12V-control signal. In practice, you probably would use only one of the methods once your C 245BEE is installed.
FRANÇAIS
AUTOMATED TURN-ON LOGIC (ATO LOGIC) The C 245BEE may be turned ON in any one of three discrete ways for complete system flexibility - from the front panel standby button, the 12V-TRIGGER circuit or by the input signal-sensing circuit. The ON/OFF power control is managed by the Automated Turn-On logic or ATO Logic circuit that requires the C 245BEE to be switched back to standby mode in
